As the largest nonprofit health data network in California, Manifest MedEx (MX) is an integral part of the state’s health data infrastructure, exchanging more than 38M health records across a network of 18 health plans, 140+ hospitals, and 2600+ providers. Committed to improving data quality and value to our network participants, Manifest MedEx was one of three original participants in the NCQA Data Aggregator Validation Program pilot in 2020 and has since earned the NCQA Validated Stream designation for four consecutive years, with 12 health plans utilizing NCQA-validated data to save time and reduce the burden of HEDIS® reporting. In January 2023, MX partnered with Clinical Architecture to pilot improving data quality by standardizing and mapping code and descriptions so that higher quality data could be provided to health plans. This year, MX is pursuing including this mapping in the NCQA Data Aggregator Validation Program, which provides a tremendous benefit to health plans. Hear from MX’s Chief Information Officer, Jason Buckner, and Clinical Architecture’s Executive Vice President of Client Services, Carol Macumber, who will share the results of the pilot and how MX will be using Clinical Architecture to improve data quality for participating health plans.
